# Layer Information
To display layer information:
1. Click on and then on **More information** to open the **GENERAL** panel. Several information are presented there:
* Number of layer features that are visible on the map. The number varies as you navigate the map.
* Extent: X and Y indicate the position of the southwest point of the layer, width and height indicate the layer extent in meters from this point.
* Date of production: this is metadata.
* Metadata: information about the data in the layer such as quality indicators, the organization producing the data, update dates, etc.
Metadata may be missing.
2. The **Transparency** function, available for raster data layers, allows you to adjust the transparency level between 0% (default) and 100%. The transparency level is saved when you save your map ([Create and Manage Customized Maps](/e/applications/jmap-ng-user-guide/i-wish-to.../create-and-manage-customized-maps.md) section).
3. Click on the **THEMATIC(S)** and/or **FILTER(S)** tabs to display these panels.
4. Click **Back** to return to the **Layers** panel.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs-jmapserver-lima.k2geospatial.com/e/applications/jmap-ng-user-guide/the-data/data-layers/layer-information.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
